BAIBBITTING TOOL OR MOLD.

Specification of Letters Patent. I

Patented July 2', 1918.

Application filed December 8, 1917. Serial No. 206,320.

ing at Newark, in the county of Essex and State of New J ersey; haveinvented certain new and useful Improvements in Babbitting Tools orMolds, of which the following is a specification.

The present invention relates to means for facilitating the casting ofliners of brass or babbitt onto so called truck boxes or the desired'thickness.

driving boxes of axle bearings for 1000- motives or the like, whichliners usually are employed to fill the gap or space between the hub ofa wheel and the bearing box.

According to the hitherto used process of applying such liners, the boxis clamped in a planing machine and the liner which has been first castinto the proper shape is screwed to the box and then planed off to Suchmethod obviously renders'the work more or less complicated requiringseparate men for casting and planing the liner. There is also much wasteof material occasioned by. this method as the scrapings of the expensivemetal falling to the ground mix with dust and other materials andrequire additional labor to separate them if it is desired to recuperatethe metal. The recuperated metal when heated again loses its resistingpower and becomes prac-- tically valueless.

The object of my invention is therefore to do away with these drawbacksand to provide means whereby much labor can be saved and waste avoided.This is accomplished by providing a tool which can be easil clamped orotherwise removably applied to the hub end of the bearing and which"will form a sort of mold to receive the material cast and to form theliner at once of the desired thickness and size, dispensing with anysubsequent finishing work. 'With some bearings particularly those knownas driving. wheel boxes and which apart from the hub liner also haveinner liners the clevice employed must be some what modified as thethicknesses of the inner parts as will be hereinafter more fullydescribed and set forth in the appended claims. I Reference is had tothe accompanying drawing in which similar reference characters denotecorresponding parts and in which Figure 1 is a sectional bottom view ofa truck box and of my device applied .to the hub end thereof showing theliner cast onto said end; Fig. 2 is a section on line 2-2 of Fig. 1showing'the truck box lying on its side with the device applied to thehub end thereof and the metal liner cast onto it; Fig. 3 is a top planview of the device proper; Fig. 4 is a bottom plan view thereof; andFig. 5 is a perspective view of a truck box with the liner cast onto itshub end.

Referring in detail to the drawing 10 denotes an ordinary truck box suchas used on bearings of locomotive axles, the hub end of which is to beprovided with a liner 10 of brass or babbitt. To facilitate the castingof the said liner I provide a tool forming thesubject of my invention.

The tool comprises an iron or steel plate .12 of substantiallyrectangular shape and corresponding in size with that of the end facesof the box and preferablycomposed of two superposed layers or sections12, 12 removably joined together by screws 13 or otherwise for thepurpose hereinafter to be mentioned. The upper section 12 is provided onits outer face with two upwardly projecting and laterally slanting loopsor handles 14 which as in the example shown jectinghl-pwar dly therefromnear each end thereof and adapted to pass through perforations in thesaid flanges. The screw bolts carry each at their upper ends nuts 19between which and the flanges are mounted spiral springs 20. Theclamping bars 16 are adapted to engage the under surfaces of the flanges10 of the box at the hub end of the latter and on the tightening of thenuts It also is provided with lateral against the tension of the springs20 to clamp the plate 12 in position on the said hub end of the "box.The sections 12, 12 have their inner faces planed to form even andsmooth surfaces. Projecting centrally from the inner section 12 is a dane 21 sub stanti-all-y of U-shaped configuration to correspond in shapeand size with and to snugly fit in the hollow 10 of the box 10. Aroundthe flange 21 the inner section 12 has a recess 22 as shown in Fig. 4%,which in form and size corresponds with those of the liner to be cast.Thefiange. 21 when the tool is applied is adapted to enter the hollow10" and the inner surface of the section 12 is adapted to rest evenly onthe surface of the hub end of the box with the recess 22 surrounding-lthe top and sides of the flange forming thus a mold into which the brassor babbitt is-cast to form the liner 10. An opening 1O provided in. theupper section and leading into the recess 22 serves as a charge openingfor the molten metal. Working in threaded openings provided in the plate12 are four pressure screws 24 which project upwardly and normally arescrewed outwardly so that their inner ends do not protrude below theinner snrfaceof the section12", When the metal has been cast and it isdesired to remove the tool from the boxthe screws 24 are screwedinwardly "to press against the body. oi the box and. to

" lift the plate therefrom against the tension of the clamping springs20.

It will be seen that by means of this device the liner can be easily andreadily cast onto the box without any waste of material and withoutrequiring subsequent finishing work such as planing or the like as is reqnired with the old process. The-material cast into the hole or recess22 is evenly distributed around the edges of the hollow 10 of the box toa thickness and width which is determined by the thiclmess of the innersection ofthe plate and the size of the recess 22 provided in the innersection. The bottom of the upper section 12 which covers the openin orrecess 22 being also even and smooth will produce a finishedsmoothsnrface of the linerso that no subsequent work will be required,

The thickness of the liner orits width or both may be Varied accordingto require ments and this can be done by simply exchanging the lowersection of the plate for another of a greater or smaller width and witha larger or smaller recess as the case may be. To this end the platel2is made of two layers removably connected together by the screws 13 ashas been described. Or the thickness of the liner cast may bevaried byloosening the screws which connect the two layers of the plate ,12 so asto permit them to be separated slightly from each other.

Since the construction can be modified in many other ways withoutdeparting from the spirit of my invention 1 do not wish to limit myselfto the details described and shown.

hat I claim and desire to secure by Letters Patent is: j

1. A tool for facilitating the casting of hub liners on bearing boxes,comprising a plate having on its lower face a recess closed at its topand a flange projecting centrally from said lower face and adapted tofit in .the hollow of the box, the parts of the lower face of said plateoutside of said recess being even and adapted to rest evenly on-thesurface of the hub and of the box, and the space formed between thewalls of the recess, the top surface of the box and the circum ferenceof the flange being adapted to con stitute the mold.
